It seems to me that the house pieces from Skyrim Creation Kit are maybe too high poly... I wonder if lower poly, well textured imported graphics wouldnt allow the creation of much larger cities... probably, we would need big internal walls in the city dividing the city into cells, so as to not overburden a single place. the objective is realism and immersion plus having the setting for inumerous possible "urban" mods... like maybe a Thief mod. What can we have in a realistic medieval city? For instance, obviously, if you have a big city, you will have many different businesses, including several competing with each other (selling similar stuff). Also, instead of so many general stores, we would have more stores dedicated to one kind of item... like a brooms store... a store selling firewood... a bakery, a store selling only silver stuff, other selling only tapestries, SEVERAL taverns and inns, etc, etc, etc.
